ADJUSTABLE CASING FOR PNEUMATIC STACKERS.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application tiled February 4, 1907. Serial No. 355,529.

To all whom it may concern:

Be it known that I, CHARLES E. VAN OsDoL, a citizen ot the United States, residing at Greensburg, in the county oi Decatur and State of Indiana, have invented certain new and useful Improvements in Adjustable Casings for Pneumatic Stackers, ot which the following is a specification.

The object oi my invention is to produce a blast tanmember for pneumatic straw stackers, preferably entirely of metal, which may be readily adjustable in its dimensions in order to Vit any one of a number ot difterent sizes or makes ot' threshing machines or other simi# lar crop treating machines.

The accompanying drawings illustrate my invention. Figure l is a side elevation of an embodiment ot my invention; Fig. 2 an end elevation, Fig. 3 a section on line 3 3 of Fig. 2; Fig` 4 a section on line 4 4 of Fig. l.

In the drawings l() indicates side sills j reie1ablyA formed oi metal tubes, and each ol said sills carries a box ll adapted to receive a shaft of a suitable blast fan to be mounted in the casing l2. The casing l2 is provided with a delivery spout I3 which, at its outer end, has a substantially vertical cylinder portion I4. Leading into the eye oi' the ian casing l2 is the usual inclined hopper l5 which extends across the frame. The two sills l,0-,l0 are connected at their outer ends by a transverse sill composed of a pair of members 1G and I7 one telescoped within the other and provided with fastenin'g means I7/ by which they may be held in any desired 3() position ol adjustment. Secured to each sill l0 are two uprights l 8-18 connected at their upper ends by a bar 19, said parts being conveniently ot commercial angle iron, Secured to each pair of uprights I8 is a side plate 20 which extends between the sill 'l0 and the beam I9. Secured to each beam It) is a pair of uprights 2l, to which is secured a plate 22 which is in the same plane as plate 20 and supplements said plate. Adjustably connected to each upright 2l by means ot' suitable bolts or other fasteners 23 is an upright 24 and the upper ends ot each pair of uprights 24 are connected by ahorizontal beam 25. Secured to beams 25 is a vertical plate 26 which is provided at an intermediate point with a horizontal ol'lset 27 so that its lower edge may overlap the upper edge oi plate 22, the arrangement beingsuch that uprights 24 may be adjusted vertically upon uprights 23, while at the same time maintaining a continuous side wall composed of the overlapping plates 22 and 26. Each beam 25 carries a horizontal top plate 29 and the two top plates overlap at their inner edges so as to form a closed top forthe casing. In order to complete the structure I provide two transverse angle irons 30-30 which are secured at one endto one of the beams 25, and the two beams 31-3] which are secured to the other beam 25 and which overlap angle irons 30 at their innerV ends, being"J attached thereto by bolts or other suitable fastenings, as 32, in the manner shown, so that the two beams 25-25 may be separated or brought together by an adjustment of the overlapping angle irons 30 and 3l.

The rear wall oi the casing is formed by three pairs oi overlapping plates. A plate 40 is secured to one rear upright 18 while a plate 4l is secured to the other upright 18, the inner ends of the plates 40 and 4l overlapping, as shown. Secured to one rear upright 2l is a plate 42 and secured to the other rear upright 2l is a plate 43, and these plates overlap each other at their inner edges. Secured to one rear upright 24 is a plate 44, the lower edge of which overlaps the upper edge of plate 42, and secured to the other rear upright 24 is a plate 45, the lower edge ot which overlaps the upper edge of plate 43, the inner edges oi plates 44 and 45 overlapping, as shown. By this arrangementthe casing may be increased both in height and in width while still maintaining continuous walls, the arrangement being such that, by proper adjustments of the parts, the forward open end oi the casing may be slipped over the rear en d of any threshing machine, or other crop treating machine, and held in place by any desired means. The two uprights 24 are provided with brackets which are connected by a suitable cross bar 5l, to which is attached the turn-table platform 52, the

turn-table 53 oi any pneumatic stacker being mounted the adjustments oi the parts may be.

I claim as my invention:

1. A pneumatic attachment for crop-treating machines comprising a plurality of overlapping metallic sheets, and a plurality of overlapping frame members connected by means permitting, adjustment one upon the other to vary the internal dimensions of the casing.

2. A pneumatic attachment for crop-treating machines l comprising a plurality of overlapping metallic sheets, and

a plurality of overlapping frame members connected by means permitting; adjustment one upon the other to vary the internal dimensions of the easingy and a fan housing.

3. A pneumatic attachment for crop-treating machines comprising a casing composed of a pair of overlapping lower sections one of which carries a fanlhousing, a pair of overlapping upper sections which also overlap the lower sections, and means for clamping the several sections together in various positions of relative adjustment whereby the internal cross dimensions of the casing may be varied.

In Witness whereof, I, have hereunto set my hand and seal at Indianapolis, Indiana, this twentysixth day of January, A. D. one thousand nine hundred and seven.
